Can a Michigan Dispensary Change the Expiration Date on the Package?

A Michigan dispensary can't change the expiration date on the package by typing a new one into the state system. As of October 28, 2026, adult-use retailers, provisioning centers, and tribal retail shops can't add or edit that date in Metrc.

By Jamie, grower at Divine Toke. Divine Toke is Sun+Earth Certified.

This isn't legal advice. I'm reading the bulletin and the Michigan rules, and I grow the flower.

Can a Michigan dispensary still edit the date in Metrc? #

No. Effective October 28, 2026, three kinds of Michigan shops can't add or edit an expiration date in Metrc. The bulletin is MI_IB_0118. Metrc distributed it on October 14, 2026, and the effective date on the sheet is October 28, 2026.

Metrc and the Michigan CRA say they're giving licensees a heads-up on a facility permission. That permission allows or restricts adding or editing expiration dates. The shops named on the sheet lose the add and the edit.

The bulletin doesn't say shops had been changing dates. It doesn't tell a story about a bad sticker or a named counter. It names the permission, the day it changes, and the licenses.

Metrc is the computer the state uses for the package tag. The Michigan rules call that computer the statewide monitoring system. This bulletin is about one field in it, the expiration date, and about who may type in that field.

What the bulletin settles	What it says
Who loses the add and the edit	Adult-use marihuana retailers, MMFL provisioning centers, and retail tribal marihuana businesses
When	October 28, 2026
When the sheet went out	October 14, 2026
What else changes on the Metrc screen	Nothing else in the expiration function, and nothing else in the Metrc UI
Whether it says shops had been rewriting dates	It doesn't

Which Michigan shop licenses lost the edit? #

The removal sentence names adult-use marihuana retailers, MMFL provisioning centers, and retail tribal marihuana businesses. A grower license isn't in that sentence. A processor license isn't in it either.

Here's the plain version of those three shop words, because the bulletin uses the statute spellings.

• An adult-use marihuana retailer is the 21-and-up counter. That's the shop most people in Detroit mean when they say dispensary.
• An MMFL provisioning center is the medical shop license. MMFL is the medical side. A patient card and an adult-use ID aren't the same door, and this bulletin still names both kinds of counters.
• A retail tribal marihuana business is the tribal retail shop on the bulletin's list. The sheet uses those words. I'm not folding every tribal license into that one line.

A Michigan grower and a Michigan processor still aren't named as losing the add or the edit. If your jar came from a grower and a processor put the pack together, this bulletin doesn't say those two licenses lost the same key.

License	Named in the October 28 removal sentence?
Adult-use marihuana retailer	Yes. Can't add or edit the expiration date in Metrc.
MMFL provisioning center	Yes. Same permission loss.
Retail tribal marihuana business	Yes. Same permission loss.
Grower	No. The bulletin doesn't remove the permission from a grower.
Processor	No. The bulletin doesn't remove the permission from a processor.

That table is the whole accusation the sheet supports. It isn't a list of shops that got caught. The bulletin doesn't name a shop.

What stayed the same on the Metrc screen? #

The bulletin says there are no other functional changes to Metrc's expiration date functionality or the Metrc UI. The field can still sit in the system. Who may type in that field changed for those three shop licenses.

So a screen that still shows a date isn't proof the shop can rewrite it. The permission is the change. The layout isn't a new layout.

Two more lines from the same sheet matter if the register acts weird.

• Metrc says API integrators were notified. Those are the software companies that plug into Metrc.
• The sheet tells the licensee to talk with the point-of-sale provider so workflows in that third-party system stay intact.

If you're the person buying, you don't call the register company. A confused screen is the shop's software problem. It doesn't print a new date on your bag. The date you can check is the one already on the package.

What date has to be printed on a Michigan edible? #

A shelf-stable edible has to state a product expiration date, and once that label is on, a licensee can't change it or stick on a later one. That's R 420.403(11). The notes on that page say 2022 MR 5, effective March 7, 2022.

The same subsection starts with a food rule. A producer can't make an edible that needs time and temperature control to stay safe. The end product has to be a shelf-stable edible, and it has to state this information:

• A product expiration date. After that date the edible is no longer fit for consumption, and it has to be destroyed.
• Once a label with that date is affixed, a licensee can't alter the date.
• A licensee also can't affix a new label with a later expiration date.
• The date has to consider the edible's quality and characteristics, the packaging, and the customary conditions from product to sale.

That's the printed-date rule. It's an edible sentence. The Metrc permission change doesn't rewrite it, and it doesn't replace it. One is a label stuck on a shelf-stable edible. The other is who may type a date into Metrc after October 28.

The look of the pack, including the candy rules, stays on the edible packaging page. I'm not redoing that page here.

The sale-label rule for an edible points at a different slice of the same section. R 420.504(2) says an edible sold by a marihuana sales location has to comply with R 420.403(7) through (10). The expiration print line is subsection (11), the next one. Read them as neighbors, not as one sticker.

Infused product also carries the date it was produced. That's R 420.403(7)(e), on the same Cornell page. Produced date answers when it was made. Expiration date answers when the edible rule says it isn't fit to eat. Don't treat those two lines as twins.

Does the flower label list an expiration date? #

The general sale label names a harvest date if it applies, and it doesn't name an expiration date. R 420.504(1) is the list a container, bag, or other holder has to carry before a sales location sells or transfers the product.

The lines on that list include the cultivator or producer name and license, the package tag from the statewide monitoring system, net weight, the lab's THC and CBD numbers, the lab name, the universal symbol, and the warning block. Item (c) is "Date of harvest, if applicable."

Expiration date isn't one of those items. The print-an-expiration sentence I can point to is the shelf-stable edible rule above. A flower jar can still show a date somebody printed. This page doesn't turn that ink into a flower mandate, and it doesn't pretend the edible sentence covers the jar.

Line	Where it lives	What a shopper can do with it
Harvest date, if applicable	R 420.504(1)(c), sale label	Read it as the harvest line when it's there. It isn't the edible expiration sentence.
Date produced	R 420.403(7)(e), infused product	Read it as when the infused product was made.
Printed expiration on a shelf-stable edible	R 420.403(11)	After that date it isn't fit to eat, and a later sticker isn't allowed.
Expiration field in Metrc	MI_IB_0118	Three shop licenses can't add or edit it after October 28, 2026.

A harvest date and a lab test date can both show up on a Michigan flower label. The test date is the lab's analysis date under R 420.504(1)(h). That's a third line. It isn't an expiration date either. How to read a lab sheet is the lab tested page. A fail on that sheet is a different problem from an old date, and it has its own page, when the test says fail.

Can a Michigan shop sell past the printed date? #

No. A marihuana business can't sell or transfer a product after the printed expiration date on the package. That's R 420.502(4) in the March 7, 2022 final rules.

The next sentence in that subsection says an expired product has to be destroyed, except for the path in R 420.214c(2)(f). The sale ban is the part you can use at the counter. If the date printed on the package has passed, the business isn't supposed to sell it to you or transfer it.

The rule keys off the printed expiration date. It doesn't say every flower bag in Michigan must carry one. It says the business can't sell or transfer after the date printed on the package. If the package has no expiration line, this subsection doesn't create one.

There's a clock on destruction once the business knows the product has to go. R 420.502(6), in that same final-rule file, says the business has to destroy product that must be destroyed within 90 calendar days of when the business became aware.

That 90-day line is the business's clock. It isn't a promise that a jar in your cupboard stays good for 90 days. Keeping flower once it's home is the storage page. Storage doesn't reset a printed date.

What does the counter have to verify? #

Before the sale, a marihuana sales location has to verify the product isn't past its expiration date. That's R 420.505(1)(b), in the same March 7, 2022 final rules.

The rule's words are marihuana sales location. That's the counter, not a grow room. The check happens prior to selling or transferring to a customer. The product isn't supposed to be past its expiration date at that moment.

R 420.502(5), same file, adds a computer check before a sale or transfer. The business has to verify in the statewide monitoring system that the product hasn't been placed on an administrative hold, recalled, or ordered destroyed. That's a hold check. It isn't the expiration field, and it isn't a lab-fail lesson. The fail page already covers a bad test.

Put the two checks next to each other so they don't get mashed into one button.

• Printed date on the package: R 420.502(4) stops the sale after that date.
• Counter verification: R 420.505(1)(b) says the sales location checks that the product isn't past its expiration date.
• Hold, recall, or destroy order: R 420.502(5) says look in the statewide monitoring system before the transfer.
• Who may type the expiration field: MI_IB_0118, as of October 28, 2026, for the three shop licenses.

A Detroit second shift gets out after dark in late October. The jar's print is small under a parking-lot bulb. I've tilted a jar at a weak light like the ink was going to confess. It wasn't. Read the line under a light you trust, before the card hits the machine.

If you're a Michigan senior who checks the date before paying, use the line on the package. A parent in Detroit with a gummy should use the edible sentence, not the flower harvest line.

Where can a retailer send an expired product? #

A marihuana retailer may send a product that's past its expiration date back to the processor who made it, for destruction, instead of destroying it at the shop. That's R 420.214c(2)(f). The notes say 2022 MR 5, effective March 7, 2022.

Read the nouns the way the rule writes them.

• The sender in that sentence is a marihuana retailer. I'm not stretching it to every license the Metrc bulletin names.
• The receiver is the marihuana processor who produced that product. Not a random processor, and not a new label shop.
• The purpose is destruction. The rule says "instead of destroying" it at the retailer. It doesn't say the processor may reprint a later date and send it back out for sale.
• R 420.502(4) already points at this subsection as the exception to destroying an expired product.

The return rule is wider than expiration. R 420.214c(1) lets a sales location accept a return of product reported to have caused an adverse reaction, or product determined to be defective. That's a customer-return door. It isn't the October 28 Metrc edit.

Inside the written return policy, R 420.214c(2)(c) says product returned to a sales location can't be resold, repackaged, or otherwise transferred to a customer or another marihuana business. Subsection (2)(b) says that returned product has to be destroyed within 90 calendar days of when the business knew. The same subsection points that destruction at the waste rule.

So the retailer path in (2)(f) is a send-back for destruction. It isn't a second life for the pack, and it isn't a way to type a fresh expiration date on October 28 or any day after.

What should you read on the package? #

Read the date that's actually printed on the package before you pay. If that printed expiration date has passed, R 420.502(4) says the business can't sell it or transfer it.

A shopper doesn't get a Metrc login to fix the field. After October 28, 2026, the adult-use retailer, the provisioning center, and the tribal retail shop don't get to add or edit it either.

Use this order when the bag has more than one date.

1. If it's a shelf-stable edible, find the expiration date. A later sticker fights R 420.403(11).
2. If it's flower, look for the harvest date when the label has one. That's R 420.504(1)(c). Don't call it the expiration line just because it's a date.
3. If it's an infused product, the produced date is its own line under R 420.403(7)(e).
4. The package tag is the tracking number from the statewide monitoring system. It isn't a date.
5. If a row on the lab sheet says fail, that's the fail page, not this one.

The wider Michigan picture, taxes and license counts and the rest, lives on the 2026 industry status page. This page is only the date on the package and the Metrc key that changed.

When did each of these rules start? #

The sale ban, the counter check, the edible print rule, and the retailer return path took effect March 7, 2022. The Metrc edit change takes effect October 28, 2026. The Cornell notes and the final-rule file both carry the March 7, 2022 date. The bulletin carries the two October dates.

Day	What a shopper can hang on it
March 7, 2022	Shelf-stable edibles have to state an expiration date, and a later label isn't allowed. A business can't sell or transfer after the printed date. The counter has to check that the product isn't past its expiration date. A retailer may send an expired product back to the processor who made it, for destruction.
October 14, 2026	Metrc distributes MI_IB_0118.
October 28, 2026	Adult-use retailers, provisioning centers, and tribal retail shops can't add or edit the expiration field in Metrc.

Both sets of rules are in force in late October. The edible label rule isn't new this week. The new piece is the computer key at those three shop licenses. A harvest date from the 2022 label list is still a harvest date. The bulletin didn't turn it into an expiration date.

If you already paid and the printed date had passed, these rules still speak to the business. They don't write a refund step for the buyer. The edible sentence says that product is no longer fit to eat after the date, and it has to be destroyed. The retailer path is a send-back to the processor who made it. That's the shop's job. It isn't a home project, and it isn't a fresh date.

What can you ask before you pay? #

Ask to see the printed date, and leave the package if that date has already passed. You don't need the shop's Metrc screen to do that. The print is the line R 420.502(4) uses.

• If it's a shelf-stable edible, ask for the expiration date. A later sticker isn't allowed under R 420.403(11).
• If it's flower, ask for the harvest date when the label has one. That's the sale-label line, not the edible expiration sentence.
• If it's an infused product, the produced date is a third line. Don't let someone call it the expiration date.
• Don't ask the counter to type a new expiration date into Metrc. After October 28, the three shop licenses can't add or edit that field.
• The package tag is the tracking number. It isn't a calendar date, and it doesn't extend a date that has passed.

A budtender can still answer a plain question. "What's the date printed on this?" is enough. If they can't find a printed expiration date on an edible, that's the edible rule's problem, and the packaging page is where the rest of that pack check lives.

What if the edible has no date on it? #

A shelf-stable edible has to state a product expiration date. The print rule for that line is R 420.403(11). If you can't find that date on an edible, the label is missing the line that subsection requires. A register can't scribble one on after October 28, not for the three shop licenses, because they can't add the field in Metrc either.

The missing line and a later sticker are different failures. A missing line means the date was never affixed. A later sticker means someone tried to move a date that was already stuck on. Both sit in that same subsection. Neither one is a flower harvest date.

What if the flower jar has no date at all? #

The sale-label list asks for a harvest date if it applies, and it doesn't ask for an expiration date. A jar with no expiration line isn't a case R 420.502(4) can call a late sale, because that rule runs off the date printed on the package. A jar that does have a printed expiration date, and that date has passed, is the case the sale ban covers.

Don't fill the blank with a guess. Don't treat the package tag as a stand-in date. If a harvest date is printed, read it as the harvest. The bulletin didn't add an expiration mandate for flower, and it didn't delete the edible sentence either.

Our flower #

Divine Toke is a Michigan mail-order shop for sun-grown flower grown in living soil. We sell flower, 1 gram pre-rolls, a 20-pack of 20 one-gram joints for $120, Honey Bananas solventless rosin, and Sundog Bio Hash. Honey Bananas rosin is the same flower run with ice water and heat, no solvents. Sundog is bio hash.

Edibles aren't on our menu. The shelf-stable edible date rule is for a pack you buy from a shop that sells them. When a package from us shows up, read whatever date is printed on it. We sell by mail.

FAQ #

Did the bulletin say Michigan shops had been changing dates? #

No. MI_IB_0118 describes a permission update, and it doesn't say shops had been changing dates. The bulletin names who can't add or edit the field after October 28, 2026. It doesn't name a shop, a city, or a past edit. Treat it as a lock on the key, not as a bust list.

Are Michigan growers and processors in the removal sentence? #

No. The removal sentence names three shop licenses, and a grower or a processor isn't among them. Adult-use retailers, MMFL provisioning centers, and retail tribal marihuana businesses lose the add and the edit. The Metrc bulletin stops there. Don't tell a grower they lost a key the sheet never mentions.

If the bag and the computer disagree, which date blocks the sale? #

The sale ban uses the printed expiration date on the package. R 420.502(4) in the March 7, 2022 final rules says the business can't sell or transfer after that printed date. The Metrc field is the computer entry the three shop licenses can't add or edit after October 28. You can see the print. You can't audit their screen from the sidewalk.

Is a harvest date the same thing as an expiration date? #

No. R 420.504(1)(c) calls for a date of harvest, if applicable, and that list doesn't name an expiration date. Harvest is when it was cut, when that line is on the label. The expiration print sentence for a shelf-stable edible is R 420.403(11). A produced date on an infused product is R 420.403(7)(e). Three different lines.

Can someone stick a later date on a Michigan edible? #

No. Once the expiration label is affixed, a licensee can't alter it or affix a new label with a later date. The edible rule is R 420.403(11), and it took effect March 7, 2022. The date also has to consider quality, packaging, and the conditions the edible usually sees from product to sale. The candy-pack rules sit on the edible packaging page, and they aren't repeated here.

How long does the business have to destroy an expired product? #

R 420.502(6) gives the business 90 calendar days from the day it knew the product had to be destroyed. That sentence is in the March 7, 2022 final rules. A retailer may instead send the expired product to the processor who made it, for destruction, under R 420.214c(2)(f). The 90 days aren't a freshness promise for your cupboard.

Did Metrc redesign the screen on October 28? #

No. The bulletin says there are no other functional changes to the expiration function or the Metrc UI. MI_IB_0118 changes who may add or edit the date, for the three shop licenses. API integrators were already notified, and the sheet tells shops to check with the point-of-sale company. A new button layout isn't what the sheet describes.

Why does the bulletin mention the register company? #

Because Metrc told licensees that API integrators were notified, and it told them to talk with the point-of-sale provider. The point is to keep the third-party workflow intact. That's in the bulletin. For you at the counter, a software hiccup still doesn't change the date printed on the package.

Is a failed safety test the same rule as an old date? #

No. A fail on the lab sheet is a different record from a printed expiration date. The hold check in R 420.502(5) is about an administrative hold, a recall, or an order to destroy, looked up in the statewide monitoring system. What a fail means for aspergillus, pesticides, and heavy metals is on the failed test page. Don't treat a date as a lab result.

Does Divine Toke sell the edibles this rule covers? #

No. Gummies aren't what we sell. The shelf-stable edible date rule still matters when a gummy comes from a shop that sells them. Read that pack's printed date before you pay.

If the date has passed, leave it #

The printed date is the one R 420.502(4) uses, and a later sticker on a shelf-stable edible fights R 420.403(11). After October 28, 2026, the three shop licenses in MI_IB_0118 can't add or edit the expiration field in Metrc.

If you want sun-grown flower by mail, we sell flower, 1 gram pre-rolls, the 20-pack, Honey Bananas rosin, and Sundog Bio Hash. The edible pack rules live on the candy-pack page. The lab sheet lives on the lab tested page. The rest of the state picture lives on the industry status page.

If the printed date has already passed, leave that package on their side of the counter.
